BOILER-FRONT.

SPECIFICATION forming part of Letters Patent No. 673,101. dated April30, 1901.

Application filed October 3, 1900. Serial No. 31,917. (No model.)

To all whom, t may concernI Be it known that I, JOHN VANEs, a citizen ofthe United States, residing at Brazil, in the county of Clay and Stateof Indiana, have in- Vented certain new and useful Improvements inBoiler-Fronts; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. A

My invention relates to improvements in steel or wrought-ironboiler-fronts, and is more especially adapted to stationary boilers orsteam-generators.

The object of my invention is to produce a boiler-front which islighter, cheaper, and more durable than those now in general use; also,one that will not warp or crack, while at the same time it is veryornamental; also, to compensate for the contraction and eXpansion in avery simple manner; furthermore, which can be quickly set up in place,as well as taken down, and finally can be produced of thinner materialthan heretofore employed and still be stronger than the ordinarycastiron fronts. v Y

With these objects in View my invention consists of a boiler-frontrolled out of one, two, or more pieces or parts bolted together andprovided with beads or molding, thereby strengthening it and making itornamental; also, to produce an expansion-joint in the front tocompensate for expansion and contraction, and linally it consists incertain details of construction and novel arrangement of parts, as willbe more fully described hereinafter and specifically pointed out in theclaims, reference being had to the accompanying drawings, in which-Figure l represents a front elevation of my improved boiler-front. Fig.2 is a cross-section on line a; of Fig. 1. Figs. 3 and 4 are detailviews of a modified form of expansionjoint. Fig. 5 is a view of theexpansion-joint on an enlarged scale. l

In the drawings, A represents the main part of the front, made in thisinstance in two parts, which are united by an expansion-joint B andbolted or riveted together. Each side of the frontis stiened, as well asornamented, by means of a bead E, and around the circular opening forthe end of the boiler is arranged another bead d, having like functionsas bead E. The fire-doors D and the ash-pit doors C are also made ofwrought-iron or steel. The openings in the front for said doors arecurved inward around their edges, as shown at c c, stiffening them,while at the same time strengthening the front. AThe holes for the boltsemployed tovhold Vthe parts together may be slotted, as shown in Fig. 5at c e, to allow the partsv to crawl, when they are expanded o rcontracted by different degrees of temperature. On each side of thefront is arranged a bead or molding E E, which serves to ornament,stiften, and strengthen thefront. If desired, lead or asbestos packingor its equivalents may be employed between the edges of theexpansion-joint and the front to form a perfectly-tight joint. Ifdesired, two eXpansion-joints B B may be employed, one on the inside andone on the outside of the front, although I desire to use the jointshown in Fig. 4. The lng b, forming the lower or bearing part of thehinges, may be provided with studs that pass through the front and aresecured on the inside by a nut or rivet.

An ornamental cornice may be secured to the top of the boiler front,also made of wrought-iron or steel, to impart a finish to it, and byadding smoke-box doors to the extension a full or iiush front can bemade.

I am aware that broadly expansion-joints are old and have been used insteam, hot-water, and other pipes, as well'as-for other purposes; also,that sliding joints in boilers are old, but never in connection with aboilerfront, and I therefore do not claim such broadly; but,

Having thus described my invention, .what

yI claim as new, and desire to secure by Letters Patent, is-

1. A boiler-front made of wrought-iron or steel, provided with anexpansion-joint B, the beads E, E, at the sides and the bead d aroundthe opening for the boiler, as shown and specifled.

2. A boiler-front made of wrought-iron or steel, provided with anexpansion-joint, the pension-bead at each side, as and for the purbeadsE, E, at the sides, the bead d around pose set forth. 1o theboiler-opening, and the openings for the In testimony whereof I ax mysignature doors curved around theiI` edges, as shown in presence of twoWitnesses.
